SPECIFICATION formingpart of Letters Tatent' No. 725,291, dated April 14, 1 903.

Application filed November 8, 1902. Serial No. 130,531. (No model.)

To aZZ whom it may concern.-

Be it known that I, TIMOTHY B. STEWART, a

citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut,haveinven ted certain newand useful Improvements in Roofs, of which the ing, and one that can be applied to old as well as new work. One form of device by the use of which these objects may be attained is illus-' trated in the accompanying drawings, in which Figurel is a view in vertical section through a roof, showing my improvement. Fig. 2 is a view in cross-section through the chimney.

Fig. 3 is a perspective viewof the cap. Fig. 4 is a perspective view of a side flashing. 'Fig. 5 is a perspective view of an end flashing. Fig. Bis a perspective view showing the application of myimprovement to old work. Fig. 7 is an inverted perspective view of a modified form of sectional cap.

In the accompanying drawings the letter Ct denotes the roof of a building or like part that may be constructed in any well-known and ordinary manner and composed of rafters, roof-boards, and shingles or slate. An opening?) is formed through the roof, through which the chimney 0 passes. In the drawings herein this opening is shown at the highest point or ridge of an A-shaped roof; but it will be understood that the invention is equally applicable to any opening in a roof through which a chimney or like part may pass Without the aid of anything more than mere mechanical skill.

In adapting my improvement to new work the chimney is built up to a point a slight distance above the outer surface of the roof, the roof being completed about the opening and the shingles, slate, or like part beinglaid up close to the chimney. A capd is then placed on the brickwork, this cap being in the form of a pan placed in an inverted position and with a hole cl through the bottom somewhat larger than the opening through V the chimney, so that the edges of the opening will be located between the outer surface of the chimney and the wall of the opening therein. The chimney is then built up to the required height in the usual manner, the cap being secured between the layers, as shown in Fig. l of the drawings. The sides (Z of this cap are located on the several sides of the chimney and at adistance from the outer surface thereof to allow the entrance of a flashing. These sides d of the cap may extend downward to any degree to prevent the entrance of water thereunder and over the upper edges of the fiashings.

Side fiashings are formed with a wall a to rest against the side of the chimney, and a foot portion e, bent at an angle to the wall and at such angle as to rest upon the shingles or outer surface of the roof. The foot of each side flashing is extended at each end, as at e beyond the ends of the walle and in position to underlie the foot portion of the end fiashings.

The end flashings are provided with a side wallfand a foot f. The side Wall of the end flashing is bent, as shown at f, to lap over the ends of the wall e of the side flashings. The foot f may be bent to angular form, as shown in the drawings, to pass over the ridge and lie on the roof on each side thereof, or if the chimney-opening and chimney are entirely on one slanting portion of the roof or on a roof of other construction, as a flat roof, it will be understood that this foot will be located and disposed with reference to the Wall placed in position the cracks may then be filled with mortar, and the cap thus secured in place. The side and end flashings will be constructed and applied in the same manner as hereinbefore described.

The foot portion of each flashing is provided with a loop or loops g, secured to the flashing in any desired manner, and a Weight h is inserted through these loops and serves to hold the flashing securely in place. In cases where the chimney opening passes through the ridge of the roof the weights applied to the end flashings may be formed in two sections united by a flexible connection 11, passing over the ridge. These weights may extend downward to a point opposite or beyond the ends of the weights on the foot of the said flashings, and thus prevent the latter from moving endwise out of the loops, as plainly shown in Fig. 2 of the drawings.

It is obvious that the details of construction may be departed from to a considerable extent and that the parts need not lap the one upon the other in the form as herein shown, but that other forms of construction may be employed and yet embody the main feature of the invention, which consists in a cap made in a single piece or in sections and secured to the chimney and of a flashing placed upon the roof and with its upper edges passing underneath the side wall of the cap and located between said wall and the chimney.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In combination with a roof and a chimney or the like passing therethrough, a cap secured to the chimney and having downwardlyextending side walls and a sectional flashing comprising two sections each having a foot portion resting upon the roof and a side portion extending upward within the cap and two other portions arranged to overlap the edges of the first-named portion and with integral and continuous foot portions passing over the ridge of the roof.

2. In combination with a roof and a chimney or like part passing therethrough, a cap secured to the chimney and having downwardlyextending side walls, a sectional flashing comprising side and end members, the side members provided with foot portions resting on the roof and projecting beyond the upturned side members, the end members having continuous integral foot portions passing over the ridge of the roof and adapted to underlie the foot portion of the side members.

3. In combination with a roof and a chimney 'or like part extending therethrough, a flashing having a foot portion resting upon the roof and a side portion resting against the chimney, means for securing the side portion in position, and a weight removably secured V to the foot portion.

4. In combination with a roof and a chimney or like part extending therethrough, a cap extending around the chimney and having downwardly-extending side walls, a flashing having a foot resting upon the roof and a side part extending upward between the side of the cap and the outer surface of the chimney, and a weight removably secured to the foot.

5. In combination with a roof or like part and a chimney extending therethrough, a cap having its bottom portion extending into the walls of the chimney and downward-extending side parts, a flashing composed of sections each having a foot resting upon the roof and a side part extending upward between the side part of the cap and the outer surface of the chimney, and a weight removably secured to the foot portion of the flashing.
